2000 SLX impeller vs. 2001/MSX
So, what is the difference between the two 7.0 OEM nujets? I know some seem to prefer the 01SLX/MSX prop. Any reason why?

I've been told that the '01 MSX prop is a tweeked 7.0, and set up for more hole shot/bottom end.
I can't verify this, but I've been told that that prop is slower than the stock '00 7.0.

I've swapped pumps between my 00 SLX and my 03 MSX 140 and seen absolutely no difference whatsoever for what it's worth...
No on that same token I've swapped pumps when one had a OEM NuJet and the other a aftermarket NuJet (still same 7.0) and the OEM is consistently a little faster (not more than .5 mph but for us speed merchants every little bit helps)...And yes this was a back to back test...Ran it, pulled it up on the trailer, swapped pumps, and ran them again...
The biggest difference I can see between the two is that the OEM has a hollow hub with spyders and the aftermarket has a solid hub...There is a noticeable weight difference between the two...I've also been told by a reliable source that the OEM's have a little more blade length but I've no way to personally verify that...
As for the difference between the 00 SLX and 01 SLX prop I've not experimented there (although I've been told they're a little different as well...)

The 01slx/msx Is Not A 7.0 Prop,its Listed As .445 Overlap.it Definately Has More Take Off And Better Midrange But The 7.0 Is About 1.5 Mph Faster.after Tweaking The 7.0 I Have Gotten It To Hook Up About The Same As The 01.

Leading Edge Closest To The Hub On The Back Side,grind Down The Excess Buildup

The MSX prop is listed as .445 clearance, overlap, and carries the NuJet 602 designation.
I believe that the difference is as previously stated, the 602 is geared more towards acceleration through alteration of bladelength and overlap.
